Marvel Studios is running a contest on the Facebook page for Iron Man 3, where fans can unlock new armor suits for a chance to win a trip to the L.A. premiere on April 24th. As a result, we have our first look at the Mark 33, an "enhanced energy suit" known as the "Silver Centurion," and the Mark 40, a "hyper velocity suit" dubbed "Shotgun." Check out these new photos, then to unlock more armor suits for your chance to win a trip to the premiere next month.
